JAMES F. DANOW ADJUSTABLE BREAD DSIPENSER WITH EJECTOR- CONTROLLED CLOSURE Sliced bread is normally packaged by means of a wrapper tightly folded and secured about the bread. Once the wrapper is broken the slices of bread may be removed therefrom for consumption purposes. Such a conventional packaging technique oftentimes proves unsanitary and does not maintain the bread in a fresh condition over extended periods of time. In addition, restaurants and the like require expeditious and efficient removal of the bread slices when they are served during meals.

An object of this invention is to provide a low cost and noncomplex dispenser for expeditiously and efficiently dispensing articles such as bread. The dispenser comprises a boxlike container adapted to retain a stack of sliced bread or other articles therein. Spring means are constructed and arranged at one end of the container for urging the bread towards a dispensing means mounted at a second end thereof. The dispensing means comprises a plunger movably mounted on the container to be actuated to remove one or more bread slices out of the container. If so desired, means may be provided for adjusting the number or size of bread slices dispensed upon a single actuation of the plunger.

Other objects of this invention will become apparent from the following description and accompanying drawings wherein:

FIG. 1 is an isometric view of a bread dispenser with th container thereof partially broken away;

FIG. 2 is a longitudinal, cross-sectional view taken in the direction of arrows 2-2 in FIG. l,-but showing a plunger employed in the dispenser in a partially depressed position;

FIG. 3 is a cross-sectional view taken in the direction of arrows 3-3 in FIG. 1;

FIG. 4 is an isometric view of a plunger employed in the FIGS. l3 bread dispenser;

FIG. 5 is a partial, side elevational view of a modified bread dispenser with the container thereof partly broken away and parts sectioned; and

FIG. 6 is a partial, side elevational view of a further modified bread dispenser with the container thereof partially broken away and parts sectioned.

. The bread dispenser illustrated in FIGS. l-4 comprises a stationary boxlike container arranged along a longitudinal axis thereof. The container forms a closed chamber 11 of rectangular cross section adapted to retain a stack of sliced bread a therein. A cover plate 12, substantially forming the containers top wall, may be connected by a hinge 13 to a vertically disposed rear end wall 14. Thus the chamber may be exposed to place the bread therein by lifting the cover plate by means of a knob 15 secured thereto.

A rectangular pusher plate 16 is reciprocally mounted in the chamber and guided in its movements by cover plate 12. opposed sidewalls l7 and 18 and a bottom wall 19. A coil spring 20 (FIG. 2) is preferably arranged between fixed end wall 14 and the pusher plate to provide a biasing means along with the pusher plate. The biasing means is arranged adjacent to a first end of the container for urging the bread along the containers longitudinal axis and rightwardly towards a second end thereof. The bread dispensing means comprises a guillotinelike plunger 2l having a vertically disposed plate portion thereof reciprocally mounted for movements transverse to the containers axis.

The plate portion projects through an elongated slot fonned between cover plate 12 and a stationary top plate portion 22 secured to a front end wall 23. As clearly illustrated in FIGS. 1 and 3, pins 24 and 25 are secured exteriorly on the sidewalls and carry tension springs 26 and 27 thereon, respectively. The springs comprise reset means respectively secured to pins 28 and 29 which project through vertically disposed slots 30 and 31 formed in the opposed sidewalls. The latter pins are respectively secured to vertically disposed prong portions 32 and 33 secured to opposite ends of a horizontally disposed flange portion 34, extending towards the second end of the container, to form a U-shaped dispensing bracket substantially encompassing a bread slice.

Opening means comprises an elongated and rectangular slot 35 formed across and through bottom wall 19 and in juxtaposed relationship to the plunger for bread-dispensing purposes. A trap door 36 is pivoted by pin 37 to the bottom wall and is adapted to be opened by the pointed ends of juxtaposed prongs 32 and 33 during the bread-dispensing function. A spring 38 is mounted on pivot pin 37 to normally retain door 36 closed when the plunger is maintained in its raised, dotted 'therebetween, formed on an axially movable adjustment plate 43. The adjustment plate may comprisea rectangular configuration having a width slightly less than the distance between sidewalls l7 and 18 to prevent rotation thereof.

Thus rotation of knob 39 will selectively align an arrow 44 formed thereon (FIG. 1) with one of a plurality of indicia means 45 to select a bread slice thickness and/or the number of bread slices to be dispensed. In the illustrated position the adjustment means is positioned to allow only one slice of bread to be dispensed at a time. Although opening 35 (FIG. 2) is illustrated for allowing a maximum dispensing of two bread slices it should be understood that the container could be elongated and the opening enlarged to dispense three or more such slices. Also, the configuration of chamber 11 could be suitably reshaped to accommodate it for the retention and dispensing of articles other than bread.

chamber II is empty cover 12 is lifted by knob 15 to expose I the empty chamber. Pusher plate 16 is depressed manually against spring 20 a sufficient amount to permit the stack of bread slices to be loaded into the chamber between the pusher plate and adjustment plate 43. The lower knife edge portion of the plunger projects vertically below flange portion 34 to positively separate the discharged bread slice from the next adjacent one.

Flange portion 34 functions to then engage and move a piece of bread out of the dispenser through aperture 33. Trap door 36 is gradually pivoted to a fully opened position by the lower ends of prongs 32 and 33 and the bread is thus positively guided out of the dispenser. Release of the plunger will automatically permit the reset means comprising springs 26 and 27 to return it to its normally raised position (R).

FIG. 5 illustrates a modified dispensing means for removing at least one bread slice out of dispenser 10a. Such dispensing means comprises a plunger 21a (shown partially depressed) reciprocally mounted through an elongated slot formed in a top cover plate 12a. The plate is secured to a horizontally disposed flange portion 34a which is secured to two opposed prongs, one of which is shown at 320, corresponding to prongs 32 and 33 of the first described embodiment. An upstanding flange 46 is secured to flange 34a and has a flexible sheetlike member 47 attached thereto.

A tensioned coil spring 48, located interiorly of the container, is attached between member 47 and a stationary pin 49 attached to cover plate l2a to normally urge the plunger to a retracted position. A guide bracket 50 may be secured between sidewalls 17a and 18a of the dispenser to guide movements of the spring and the flexible member. Trap door 36 as well as the adjustment means comprising knob 39 may also be utilized therein.

FIG. 6 illustrates a further modified dispensing means 10b comprising a vertically disposed plunger 21b (shown partially depressed) having the vertical plate thereof secured to a horizontally disposed flange 34b and a pair of opposed prongs, one of which is shown at 33!). A second horizontally disposed flange 51 is secured between the lower ends of the two prongs and functions to normally cover a rectangularly shaped discharge chute 52 which replaces trap door 36. ln addition, flanges 34b and 51 are suitably spaced at a distance substan tially equaling the height of a bread slice.

Means, such as springs 26 and 27 or spring 48, may be utilized for returning plunger 21b to its normally retracted position after it has been fully depressed for bread dispensing purposes. Bread slice adjusting means comprising knob 36 and its attendant structures may also be employed therewith. It should be further understood that the FIGS. l-4, 5 and 6 dispensers may utilize a pivoted cover plate, a pivoted rear end panel or other suitable means for loading the container with a stack of sliced bread. For example, a tongue-andgroove arrangement may be employed between cover plate 12 and sidewalls l7 and 18 to permit linear removal of the cover plate for loading purposes.
